Speedfit are about the worse plastic fittings.

To be fair, if you cut the pipe properly then all is well. Thickos who
can't use tools and\or pipe properly would find anything useless.

Mr, Pole, I would go along with that.

Get a combi

Only one?


To be fair, I don't think I would even contemplate returning to DIY plumbing
if speedfit had not come along. I've been very careful when using speedfit
to cut pipe squarely and I always clean pipe ends as though I am going to
sweat them which may seem extreme and obsessive. My father was a complete
nut about cleaning things up before assembling them and somewhat drilled the
practise into me, be it car mechanics, electrics or plumbing. I suspect it
was a carry over from his days in the services.

So far I have never had a problem with 15mm or 22mm fittings for both mains
and tank/cylider feeds. Haven't tried them on c/h which is why I'm a little
anxious about using them for the straight connections and elbows in my 28mm
piping. However, they are reputedly suitable for all c/h use so I'll press
ahead with speedfit and see what happens!

I still don't know what a "combi" is unless this is referring to a combi
boiler in which case I don't understand the relevance to this thread.
